摘要
文中对一类传统的直流滤波傅里叶算法的误差进行了分析,并在研究的基础上提出了一种新的直流滤波傅里叶算法。首先分析此类传统的直流滤波傅里叶算法如何修正带有直流衰减分量的短路电流采样值,分析修正采样值的过程中误差的变化,然后利用MATLAB仿真计算了此类算法的误差规律,最后提出一种兼顾运算量和计算精度的直流滤波傅里叶算法。
This paper studies the factors that influence the error of a kind of traditional Fourier algorithm with DC filter, and on the basis of the research, a new DC filter Fourier algorithm is proposed. Firstly, the algorithm that can eliminate the decaying DC component in the transient current is presented and then the factors that influence error of this kind of Fourier algorithm with DC filter are analyzed. Followed, a simulation to observe the change of error is carried out with MATLAB and the simulation coincide with the predicted result. Finally, a new Fourier algorithm which considered computational complexity and accuracy is presented.
